    • The driving device of a solid-state imaging device comprises a driving unit for driving the solid-state imaging device in either an addition driving mode in which a plurality of pixels are added and read as a single pixel or a non-addition driving mode, and a substrate bias voltage supply for applying a bias voltage to the substrate of the solid-state imaging device according to the driving mode. The substrate bias voltage is set according to the number of pixels added in the addition driving mode so that the overflow level of the charge accumulating portion may be lower in the addition driving mode than in the normal driving mode. This suppresses the input of excess charges to the horizontal transfer path even in the addition driving mode, thereby preventing the generation of horizontal streak noise.
    • 固态成像装置的驱动装置包括:驱动单元,用于以附加驱动模式驱动固态成像装置,其中多个像素被添加并读取为单个像素或非加法驱动模式, 以及基板偏置电压源,用于根据驱动模式向固态成像器件的衬底施加偏置电压。 根据在相加驱动模式中添加的像素数量来设置衬底偏置电压,使得在相加驱动模式下电荷累积部分的溢出电平可能低于正常驱动模式。 这即使在相加驱动模式下也能够抑制对水平传送路径的过剩电荷的输入,从而防止产生水平条纹噪声。
